1-2 System Configuration
CIF Units can be connected to the following Units.
• NX-series CPU Units
• NX-series Communications Coupler Units
This section describes the system configuration for each type of Unit that
a CIF Unit can be connected
to.
The following figure shows a system configuration when
a group of NX Units is connected to an
NX-series NX1P2 CPU Unit.
You can connect the EtherCAT Slave Terminal to the built-in Ethe
rCAT port on the CPU Unit. Refer to
1-2-2 System Configuration of Slave Terminals on page 1-5 for details on the system configuration of a
Slave Terminal.
Refer to the user’s manual for the connected CPU Unit for details on
how to configure the system if the
connected CPU Unit is not an NX1P2 CPU Unit.
